Gum Disease Bacteria May Cause Heart Valve Calcification

New research links gum disease bacteria P. gingivalis to calcific aortic valve stenosis. Findings suggest oral health may prevent heart valve disease. Presented at AHA Basic Cardiovascular Sciences 2026.

This research matters because it identifies a potential biological pathway linking a common, treatable condition (gum disease) to a serious heart valve disease (aortic valve stenosis) that currently has no preventive medication. If confirmed, it could lead to simple oral hygiene measures and periodontal treatments as strategies to reduce the risk of developing this life-threatening condition. The findings also empower dental professionals to play a key role in cardiovascular prevention.
